Long-term survivors of childhood acute lymphoblastic leukemia (ALL) are at risk for neurocognitive impairment, as well as compromised hypothalamic-pituitary-adrenal (HPA) function. Dehydroepiandrosterone-sulfate (DHEAS) is an adrenal androgen commonly used as a marker of HPA function. In the general population, a low level of DHEAS has been associated with poorer cognition. At ≥2years post-treatment, we examined the association of DHEAS with attention outcomes in 35 male and 34 female long-term survivors of childhood ALL (mean[standard deviation] age at evaluation 14...

BACKGROUND: Respiratory muscle strength has been used as a tool for evaluating respiratory rehabilitation in chronic obstructive pulmonary disease. However, mouth pressure measurement evaluated by maximum expiratory mouth pressure (PEmax) or inspiratory mouth pressure (PImax) offers an indirect method for measuring respiratory muscle strength. We demonstrated the evaluation of diaphragm contractility using a mechanomyogram (MMG), which is the mechanical signal generated by the motion of the diaphragm induced by the electric stimulation of the phrenic nerve...

Staphylococcal prosthetic joint infections (PJIs) are associated with biofilm formation, making them difficult to treat; if managed with débridement and implant retention, rifampin-based therapy is usually employed. Rifampin resistance potentially challenges PJI treatment. In investigating the effects of rifampin monotherapy on methicillin-resistant Staphylococcus aureus (MRSA) foreign body osteomyelitis in rats, we previously demonstrated that rifampin resistance was selected but that it disappeared 14 days following rifampin monotherapy (1) and that rifampin resistance occurred less frequently following two rounds than one round of rifampin monotherapy (2)...

An 80-year-old woman with a medical history of mitral valve replacement with single-tilting disc prosthesis underwent transcatheter aortic valve replacement (TAVR). The tilting disc was noted to have abnormal motion after re-ballooning of the TAVR valve. Cardiopulmonary bypass was initiated, and the procedure was converted to surgical aortic valve replacement. After removal of the TAVR valve, the tilting disc moved freely. Although TAVR in patients with mitral prostheses is technically feasible, particular caution is necessary, and postdeployment dilation should be avoided...

OBJECTIVES: Several studies associated altered gut microbiota composition in preterm infants with late-onset sepsis (LOS), up to days prior to clinical onset of sepsis. However, microbiota analysis as early diagnostic biomarker is in clinical practice currently not feasible because of logistic aspects and high costs. Therefore, we hypothesized that analysis of fecal volatile organic compounds (VOC) may serve as non-invasive biomarker to predict LOS at a preclinical stage, since VOC reflect the composition and activity of intestinal microbial communities...

Foreign body-associated infection is often difficult to treat, given that the associated microorganisms are in a biofilm state. Previously, we showed that low-amperage direct electrical current (DC) reduces biofilms of Propionibacterium acnes formed on implant-associated materials in vitro Herein, low-amperage DC was compared to ceftriaxone or no treatment in a novel rat femur foreign body osteomyelitis model. A platinum implant seeded with 10(7) CFU/cm(2) as well as 10(9) CFU of planktonic P. acnes were placed into the femoral medullary cavity...

The anthropogenic discharge of phosphorus (P) into surface waters can induce the proliferation of cyanobacteria and algae, which can negatively impact water quality. Enhanced biological P removal (EBPR) is an engineered process that can be employed to efficiently remove significant quantities of P from wastewater. Within this engineered system, the mixed microbial consortium (MMC) becomes enriched with polyphosphate accumulating organisms (PAOs). To date much knowledge has been developed on PAOs, and the EBPR process is generally well understood; nonetheless, the engineered process remains underutilized...

Mitral annular calcification (MAC) is a chronic degenerative process at the fibrous base of the mitral valve. It is a feared diagnosis in the context of mitral valve operations because of the risk of severe adverse events such as atrioventricular disruption, injury to the circumflex artery during debridement, and difficult placement of annular sutures. We report a series of 3 consecutive female patients with severe circular MAC who underwent successful mitral valve replacement through a lateral minithoracotomy with use of an inverted transcatheter aortic valve...

Neural circuits reliably encode and transmit signals despite the presence of noise at multiple stages of processing. The efficient coding hypothesis, a guiding principle in computational neuroscience, suggests that a neuron or population of neurons allocates its limited range of responses as efficiently as possible to best encode inputs while mitigating the effects of noise. Previous work on this question relies on specific assumptions about where noise enters a circuit, limiting the generality of the resulting conclusions...
